Step-by-step explanation:
I hope u are asking for average speed
average speed = total distance/total time
= 225/7.5
= 30 km/h or 30 km per hour
Answer:
The markup percent on the painting is 58.3%
Step-by-step explanation:
Here, The Cost price of the painting = $120
The selling price of the painting = $190
Hence, the total profit on the painting = Cost Price - Selling price
or Profit = $190 - $120 = $70
Now, Markup % = (Gross Profit / cost) x 100
⇒Markup % =
Hence, the markup percent on the painting is 58.3%
13) b=145 because a line equals 180° so you subtract 35° from 180°
14) b=61 because it as right angle so 90 minus 29 equals 61
15) b= 23 because 360 is a full circle so you add 243 and 94 and get 337 then subtract 337 from 360
16)b=131 because you subtract 49 from 180
17) b=90 because you subtract 90 from 180
18) b=73 because of vertical angles
Answer:
The curvature is
The tangential component of acceleration is
The normal component of acceleration is
Step-by-step explanation:
To find the curvature of the path we are going to use this formula:
where
is the unit tangent vector.
is the speed of the object
We need to find , we know that so
Next , we find the magnitude of derivative of the position vector
The unit tangent vector is defined by
We need to find the derivative of unit tangent vector
And the magnitude of the derivative of unit tangent vector is
The curvature is
The tangential component of acceleration is given by the formula
We know that and
so
The normal component of acceleration is given by the formula
We know that and so
One of the easier approaches would be that of x- and y-intercepts.
Setting x=0 results in y=-10; the y-intercept is (0, -10).
Setting y = 0 results in x = 5, so the x-intercept is (5,0).
Plot these 2 points. Then draw a str. line thru these points.
